This is the entrance to a World War II bomb shelter that was located in one of the Untergrundbahn stations, although regrettably I've forgotten which one. If anyone remembers I would love to know.

And...here it is, an active rail facility, Bruckenmeisterei Werkstatt, still in existence in a railyard that's been abandoned for so long that trees are growing through the tracks and the whole place has become a park. I wasn't trespassing when I took this, by the way, but rather I found a crack in the door just barely big enough for my lens, and then I had to crop this before I posted it. That train sitting there, by the way, is an old untergrundbahn, or subway/metro train, and I have no idea what it's doing here.
